Casemiro played the full 90 minutes in Real's 6-1 Copa Del Rey's round of 32 win against Cultural Leonesa on Wednesday night after being sidelined since September with a leg injury.

Speaking after Wednesday's Cup game, Zidane told Real's official website that it was important to give the 24-year-old a full game in order to get his fitness back

"[Casemiro] felt fine. He struggled a little bit early on but that's to be expected after almost two months out. It was important for him to play a full match and he's happy and well prepared," Zidane said.

"When you look at the way we've played in midfield in our recent games, we've been strong. Casemiro has come back, he's fit and ready to help the team.

"He's with us and we'll have to see what we're going to do on Saturday, but we're going to need everyone."

Commenting further on this weekend's clash against Barcelona, Zidane said the outcome of the game will not decide the title race.

He stated: "We're not thinking about the consequences of the result, only about preparing well for the game. Whatever happens it won't be decisive.

"It's a good match against a great opponent who will certainly make it difficult for us and that's all there is to it.

"We have to be ready. Now we need to rest up and we'll start our preparations tomorrow. It won't be decisive, not at all."
